Android開發 AIDL使用自訂對象作參數或傳回值

標籤：des   android   http   java   使用   os   io   檔案   

http://www.pocketdigi.com/20121129/952.html

預設，AIDL支援對象作參數，但需要該對象實現Parcelable介面，且aidl檔案應該是該類在同一包下，需要單獨給該類定義一個aidl檔案.
定義模型類:
EnglishItem.java:

123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120121122

package com.pocketdigi.english.aidl; import android.os.Parcel;import android.os.Parcelable; import com.j256.ormlite.field.DatabaseField;import com.j256.ormlite.table.DatabaseTable;import com.pocketdigi.english.utils.Constants;import com.pocketdigi.english.utils.Des; @DatabaseTable(tableName = "listenlist")public class EnglishItem implements Parcelable {/** * */private static final long serialVersionUID = -1756522544697525757L;@DatabaseField(id = true)private int id;@DatabaseFieldprivate String title;@DatabaseFieldprivate String category;@DatabaseFieldprivate String mp3url;@DatabaseFieldprivate String lrcurl;@DatabaseFieldprivate String txturl; public static final Parcelable.Creator<EnglishItem> CREATOR = new Parcelable.Creator<EnglishItem>() {public EnglishItem createFromParcel(Parcel in) {return new EnglishItem(in);} public EnglishItem[] newArray(int size) {return new EnglishItem[size];}}; private EnglishItem(Parcel in){readFromParcel(in);} public int getId() {return id;} public void setId(int id) {this.id = id;} public String getTitle() {return title;} public void setTitle(String title) {this.title = title;} public String getCategory() {return category;} public void setCategory(String category) {this.category = category;} public String getMp3url() {return Des.decodeValue(Constants.DES_KEY, mp3url);} public void setMp3url(String mp3url) {this.mp3url = mp3url;} public String getLrcurl() {return Des.decodeValue(Constants.DES_KEY, lrcurl);} public void setLrcurl(String lrcurl) {this.lrcurl = lrcurl;} public String getTxturl() {return Des.decodeValue(Constants.DES_KEY, txturl);} public void setTxturl(String txturl) {this.txturl = txturl;} @Overridepublic int describeContents() {// TODO Auto-generated method stubreturn 0;} @Overridepublic void writeToParcel(Parcel out, int flag) {// TODO Auto-generated method stubout.writeInt(id);out.writeString(title);out.writeString(category);out.writeString(mp3url);out.writeString(lrcurl);out.writeString(txturl);}/** * 讀 * @param in */public void readFromParcel(Parcel in){id=in.readInt();title=in.readString();category=in.readString();category=in.readString();lrcurl=in.readString();txturl=in.readString();}}

Parcelable.Creator不可少。
同包下定義一個EnglishItem.aidl：

12	package com.pocketdigi.english.aidl;parcelable EnglishItem;

最後是調用介面aidl：
PlayerAidl.aidl:

123456789101112131415161718192021222324252627

package com.pocketdigi.english.aidl; import com.pocketdigi.english.aidl.EnglishItem; interface PlayerAidl {/***傳入列表**/void putList(inout List<EnglishItem> item);/***播放指定音頻**/void play(int index);void pause();/***暫停後恢複播放**/void resume();/***刪除指定項**/void delete(int position);/***停止服務**/void stopService();}
